waukee and State of Wisconsin,-and'WILBER E. RICHARDSON, residing in New York, in the county of New York an State of New York,

have invented a new and useful Improvement inOil-Pump Motors, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

I This invention relatesparticularly to certain new and useful improvements in oilpump motors, but broadly covers improvements in motors for any purpose, and has for its object to provide operatingmeans having movable'support from a moving body an capable of imparting motion to an operated means by reason of the difference in the effect produced by the movements of the body on the support and on the operating means,-

such difference in effect being due to the inertia of the operating means. p

Anotherobject'of this invention is to provide a moving body carrying an actuating means mounted to be movable With relation to the moving body and means connecting movements of the body.

Another object of this invention is'to provide a machine oil-feed pump or the like with an automatic operating means adapted to impart motion to such oil-feed pump or similar device during the movements of'the machine only and receiving its impulse from such movements of the machine.

A further object of this invention is to accomplish the above results by means of a movable weight the inertiaof which renders it less susceptible to the influence of the movements of the, engine than its support and the difference in the effects produced by such movementsyon theweight and on its support being utilized to operate the pump.

Another object of thisinvention is to vary q the degree of effect produced by the motor, as by rendering the actuating means for the.

weight-operated lever-arm adjustable toward Specification of Letters Patent. Application filed I ebruary 23,1904- Seiial No. 194,880. I

or away from theoperating-shaft controlled bysaid lever-arm.

With the aboveprimary andother incidental objects in view the invention consists of the devices and parts and their equivalents as hereinafter set forth.

In the accompanying drawings the figures represent side elevations of two modifications of oil-pump motors embodyin the principles of this invention and applie to a sight-feed oil-pump such as is shown and described in Letters Patent to ,Wilber E. Richardson, No. 661,323, dated November 6,1900.

Figure. 1 shows a form of the invention in which the lifting force of a suspended Weight ,6 5 is opposed by a second Weight, and Fig. 2

.shows a form of the invention in which the to a supporting means 2, such as the cab of a locomotive or any other body, preferably re ceiving motion from the mechanism supplied with oil by the pump, and 3 is the shaft of said oil-pump, which is capable of operating the pump mechanism when given slight oscillations. A sleeve 4 is fixed upon the shaft 3 and held rigid therewith by means of a nut 5, threaded on said shaft and preferably binding the sleeve upon a shouldered squared portion of the shaft. A socket 6 isprovided on said sleeve, in which a lever- 5 An'angular bracket 8 is given rigid support either, as here shown, upon the pump 1 or in any other manner or place, and in a perforation of its rojecting upper end, which overhangs the ever-arm 7", is-loosely mounted an eyebolt 9 with its eyeportion lowermost and its nut 10 restin upon the upper surface of the bracket. A ink 11 has its upper looped end coupled to the eye of the eyebolt 9 by a ring 12, and its lower looped end engaged in 5 the upper projecting eye13 of a weight 14, preferably a solid metalball. The lower eye 13 of said weight connects with the upper in the car 16 of a collar 17 which is slidably =mounted on the lever-arm 7, said collar being. held in its adjusted positions by a set screw 18, threaded therethrough and engaging the lever-arm 7. The upper link may be suspended from any desired portion of the movable body and may have any desired length as compared with the lower link. For

degree of movement of the ball-weight 14,

and so maybe preferred. A wei ht 19, also preferably formed of a solid metal ball, liasa central bore therethrough with a sliding fit on the lever-arm 7, and its collar 20, rigid therewith or secured thereto, carries a set-screw 21 to engage the lever-arm 7, so that the ball- =weight 1.9 may be adjusted on the lever-arm nearer to or farther from the shaft 3.

The bracket 8 is provided. with a lateral extension 22, by which the said bracket is mounted upon the pump 1, said'extension having longitudinal slots 23 therein throu h which extend bolts 24, capable of rigidy clamping the extension 22 to the casing of the pump l'when the proper adjustment is accomplished. j j The form of invention shown in Fig. 2 is similar to that shown-in Fig. 1, except that the weight 19 is omitted and in place thereof a coiled spring 25 is employed, its-upper hooked end enga ing the perforation of the depending ear "1 of the collar 17, corre sponding to the collar 17 of Fig. 1, and the lower hooked end. of said spring engaging the eye of an eyebolt 9, mounted in'theunder bracket 8, similar to the'corresponding arts above. The bracket 8 has the latera extension 22 adjustably bolted to the under side of the pumpcasing 1- orin any suitable manner or place in the same manner as with the ext'ension22.

In-operation while the supporting means 2 is making quick horizontal motions, such as are common with a locomotive-cab when un der way, the inertia of the ball-weight 14 tends to prevent its participating in such movements, and as the pump takes the movement of the support the result is-that said weight draws upwardly upon the collar 17, thereby oscillating the shaft 3 by means .of the lever-arm 7.. The weight 14 being sus pended from the bracket 8 by means of the ink connection 11 is free to swing as a pendulum, and in such movements its link connection 15 with thelever-arm 7 causes said lever-arm to oscillate the shaft 3, and so oper- 19 serving to restore the lever-arm 7 to its normal position after having been swung up- Wardly by theflweight 14,. as just described. It will be seen that the degree of movement of the lever-arm 7 depends upon the degree 7'0 of movement of the weight 14, and'shduld it be found that in a particular case the extent of movement of the parts in theirrelative adjustments is not suflicient to give the oilpumping mechanism its de'sired operation the bracket 8 may be adjusted nearerto the shaft 3 by loosening the bolts.24 and sliding the bracket extension 22 to the left, as shown in the drawings, and at the same time loosening set-screw 21 and sliding the collar 20 8c along the lever-arm 7 toward the shaft 3 to a corresponding extent. In their new adjustments the parts are again secured, and for the given amount of swing of the weight 14 relative .to the other parts the lever-arm 7 is sult the degree of oscillation of the shaft 3 is increased, and by it the operation of the pumping mechanism is correspondingly iiicreased.

With the construction shown in Fig.2 the operation is the same as that of the construction just described, the spring 25 serving to oppose the pull of the weight 14 and to return the lever-arm 7 to its horizontal position after being lifted by said weight 14. The adjustments of this form of device are alsosimi- 1 oo lar to those described for the form shown in f Fig. 1, vn'ththe exception that it is also necessary to adjust the bracket 8 in the same manner that bracket. 8 is adjusted, so as to keep the two brackets in alinementi While the part 2 has been referred to herein as the movablesupport or body, it is obvious that the bracket 8 and pump- 1,

which are intended tohave a rigid connection therewith, and therefore partake of the no movements, may be considered as movable bodies or movable supports, and itis with the understanding that these terms movable support and movable body are sufficiently broad to cover any body or'support .1 i 5 capable of movement or designated to receive movement that they are employed in the following claims. Such terms are not intended to render the combinations incomplete without the presence ofa moving en- 12o gine or cab or other body by which the parts -may be carried.

What we claim as our invention is 1. A movable support, a weight suspended therefrom, an operated means connected :25
